C1000-082 IBM Spectrum Protect V8.1.9 Administration Questions and Answers

you can change the number of versions of backups to keep with settings in the Operations Center: Backups1. If you use commands, you can use the DEFINE COPYGROUP command with the VEREXISTS parameter1.

According to IBM documentation1, the move DRMEDIA command is used for changing the DRM state of a volume. The command tracks volumes that are to be moved offsite and identifies the expired or empty volumes that are to be moved onsite.

According to the IBM Spectrum Protect™ and Spectrum Scale™ Integration Guide1, one option that should be specified when configuring a storage agent for optimal LAN-free backup and restore performance is LANFREESHM YES. This option enables the use of shared memory for communication between the storage agent and the server, which can improve throughput and reduce CPU usage.

In IBM Spectrum Protect node replication, dissimilar policies provide the ability to replicate client data between source and target servers with differing retention settings.

Dissimilar policies allow for more granular control over the retention settings of client data on the target server, which can be different from the retention settings on the source server. This means that the data can be kept for a longer or shorter period of time on the target server compared to the source server, based on the specific retention policies configured for the target server.

According to IBM documentation1, dissimilar policies provide the ability to use different management policies on the target replication server than on the source replication server. This means that you can have different retention periods, storage pools, or data types for replicated data on the target server. You can enable this feature by using the SET DISSIMILARPOLICIES command.

According to IBM documentation1, the purpose of the SET REPLSERVER command is to set the name of a target replication server for a source replication server. The command has two parameters: SERVERNAME and REPLSERVER. The SERVERNAME parameter is the name of a source replication server that you want to replicate data from. The REPLSERVER parameter is the name of a target replication server that you want to replicate data to.

According to IBM documentation1, the purpose of the SET REPLSERVER command is to set the name of a target replication server for a source replication server. The command has two parameters: SERVERNAME and REPLSERVER. The SERVERNAME parameter is the name of a source replication server that you want to replicate data from. The REPLSERVER parameter is the name of a target replication server that you want to replicate data to.

According to IBM documentation1, clients at-risk in the Operation Center are clients without successful backup based on the policy. The Operation Center shows a large number of “At Risk” clients even though backups are completing normally if the number of “At Risk” clients is larger than the number of failed client backups.
